Product catalog summary
Overview of Atlas 25+® Standard Testing Program
The Atlas 25+® program is a comprehensive durability testing initiative designed specifically for photovoltaic (PV) modules. It aims to simulate long-term environmental exposure effects, providing a more accurate prediction of module longevity compared to traditional IEC tests.
Testing Procedures
  • Condensing Humidity, Salt Spray Corrosion, UV-A/UV-B Exposure: These tests simulate various environmental stresses that PV modules may encounter.
  • Solar/Thermal/Humidity/Freeze Cycle: This involves outdoor solar tracking in diverse climates such as South Florida and the Arizona Sonoran Desert.
  • Initial, Final, and Multiple Interval Measurements: Includes visual inspections, IV curves, infrared thermographs, electroluminescence, wet leakage, and digital photography.
Testing Tiers
  • Basic: 6 months outdoor exposure in desert and sub-tropical locations, with 4 modules tested and 1 interim evaluation.
  • Standard: 12 months outdoor exposure, similar locations, with 4 modules tested and 5 interim evaluations.
  • Premium: 12 months exposure including high altitude and tropical corrosion locations, with 6 modules tested and 6 interim evaluations, plus additional elevated temperature exposure tests.
Comparison with IEC Tests
  • IEC Tests: Focus on isolated, individual stress tests for short-term failures.
  • Atlas 25+: Simulates long-term environmental exposure with combined stresses, providing a true analog of real-world conditions.
Certification and Validation
Atlas partners with SGS to provide certified test results, offering manufacturers data to support warranty and performance claims. The Atlas 25+ mark serves as a product differentiator, indicating independent third-party testing.
Conclusion
The Atlas 25+ program offers a robust framework for assessing the long-term durability of PV modules, complementing existing IEC tests by focusing on real-world environmental conditions and stresses.
